DNMA110408-RK5 WKK10S — Indexable turning insert for cast iron (Walter Tools)

DNMA110408-RK5 WKK10S is an indexable turning insert optimised for productive machining of cast iron components, combining robust geometry with Tiger·tec Silver coating technology

• Tiger·tec Silver coating for cast iron
• RK5 chipbreaker for stable chip control
• Rhombic 55° shape, 0.8 mm corner radius
• Negative rake 0° for robust turning

Longer tool life and predictable performance in cast iron turning

The DNMA110408-RK5 WKK10S insert uses a coated carbide grade from the Tiger·tec Silver family, engineered specifically for abrasive cast iron applications. The grade WKK10S balances hardness and toughness to resist abrasive wear common in grey and nodular cast irons, which reduces index changes and machine downtime. As the coating and substrate are matched for this task, the result is more consistent tool life and fewer interruptions in production, which supports higher process stability and predictable cost per component.

Geometry and chip control that improve cycle time and surface finish

The combination of a Rhombic 55° form, 0.8 mm corner radius and a negative 0° rake provides a rigid cutting edge for heavy and interrupted cuts. The RK5 chipbreaker is tailored to the fracture-prone chips of cast iron, promoting controlled chip formation and evacuation. This leads to shorter secondary operations and a better surface finish, while the stable edge geometry reduces the risk of edge chipping, enabling higher feed rates where appropriate without compromising part quality.

Practical integration into turning operations and machine shops

Designed for seamless use in standard toolholders for rhombic inserts, this indexable solution is suitable for a wide range of turning tasks on cast iron components, from roughing to medium finishing. The robust design supports reliable clamping and repeated indexing, and the insert’s characteristics simplify process setup: producers benefit from predictable results and reduced scrap rates. For specific cutting data, tooling alternatives or to verify suitability for a particular cast iron grade, Metav Werkzeuge’s consultants can supply tailored recommendations.

FAQ

Is this insert suitable for cast iron turning?
Yes. The DNMA110408-RK5 WKK10S is engineered for machining cast iron (K) and its coating and chipbreaker are optimised for that material group.

What does the RK5 chipbreaker do?
The RK5 chipbreaker promotes controlled chip formation and reliable evacuation when machining brittle, fracture-prone materials such as cast iron, reducing the chance of long, entangling chips.

Can the same insert be used for stainless steel or hardened materials?
The WKK10S grade and the insert geometry are specified for cast iron applications; different grades and geometries are recommended for stainless steels or hardened materials.

How does the Tiger·tec Silver technology benefit production?
Tiger·tec Silver combines a tailored substrate with advanced coating layers to improve wear resistance and edge stability in abrasive cast iron applications, resulting in more consistent performance and fewer index changes.

What is the advantage of the rhombic 55° shape and 0.8 mm corner radius?
The rhombic 55° form provides secure seating and cutting edge strength, while the 0.8 mm radius balances edge robustness with achievable surface quality for turning operations.
